NAME

       ldns_dnssec_verify_denial, ldns_dnssec_verify_denial_nsec3

SYNOPSIS

       #include <stdint.h>
       #include <stdbool.h>

       #include <ldns/ldns.h>

       ldns_status ldns_dnssec_verify_denial(ldns_rr *rr, ldns_rr_list *nsecs, ldns_rr_list *rrsigs);

       ldns_status   ldns_dnssec_verify_denial_nsec3(ldns_rr   *rr,   ldns_rr_list  *nsecs,  ldns_rr_list  *rrsigs,  ldns_pkt_rcode  packet_rcode,
       ldns_rr_type packet_qtype, bool packet_nodata);

DESCRIPTION

       ldns_dnssec_verify_denial() denial is not just a river in egypt

	      rr: The (query) RR to check the denial of existence for
	      nsecs: The list of NSEC RRs that are supposed to deny the existence of the RR
	      rrsigs: The RRSIG RR covering the NSEC RRs
	      Returns LDNS_STATUS_OK if the NSEC RRs deny the existence, error code containing the reason they do not otherwise

       ldns_dnssec_verify_denial_nsec3() Denial of existence using NSEC3 records Since NSEC3 is a bit more complicated than  normal  denial,  some
	      context arguments are needed

	      rr: The (query) RR to check the denial of existence for
	      nsecs: The list of NSEC3 RRs that are supposed to deny the existence of the RR
	      rrsigs: The RRSIG rr covering the NSEC RRs
	      packet_rcode: The RCODE value of the packet that provided the NSEC3 RRs
	      packet_qtype: The original query RR type
	      packet_nodata: True if the providing packet had an empty ANSWER section
	      Returns LDNS_STATUS_OK if the NSEC3 RRs deny the existence, error code containing the reason they do not otherwise
